Er, no. The native cat is either a different species or a VERY
different subspecies.

The problem with cats is that they are provided with food and
shelter, thus enabling a density of population hundreds (or, more
probably, thousands) of times higher than would occur in nature.
And, despite your claims, they are are much greater threat to
small birds than grey squirrels are.
